Ibeo Reference Sensor System

What is ibeo.Reference?

ibeo.Reference is a combination of Ibeo’s LIDAR sensor technology and the corresponding evaluation software system. The algorithms of the ibeo Evaluation Suite generate reference scenarios to create a benchmark for the evaluation of ADAS and HAD applications. Furthermore, they serve as basis for the development of new applications.

Use-cases for the ibeo.Reference system are:

You want to assess the performance and robustness of your own ADAS applications like a Blind Spot Monitoring System or a Lane Change Assist.

You want to create reference data for the evaluation of your Device under Test (DuT) system.

You want to use the reference system for the development and testing of your own ADAS applications.

Setup of the ibeo.Reference Sensor System

In the ibeo.Reference sensor systems (RSS), the reference sensors and the sensor system to be evaluated, i.e. the Device under Test (DuT), are integrated into a vehicle. Up to six ibeo LUX LIDAR sensors are attached to the vehicle in a horizontal plane. Three of these sensors are installed in the middle and on the left- and right-hand sides of the bumper. The other three are mounted to the rear bumper to generate a 360° view of the vehicle’s surroundings.

An additional rearward LIDAR sensor, the SICK LMS 500 facing the road is installed on the roof. Due to its downward tilt, the sensor is able to scan the road surface and deliver information about road markings and road boundaries.

Ibeo LUX Sensor

The ibeo LUX LIDAR sensor detects the surroundings of the sensor and/or the objects located within a 110° field of view.

For this purpose, laser beams are sent from the ibeo LUX over four levels and measure the distance and the direction (the angle in relation to the ibeo LUX) of the objects. This measurement is based on the Time of Flight measurement principle. The position of the object is indicated in the sensor or vehicle coordinate system.

Technical facts:

Embedded Feature-Based Object Tracking and Classification

Wave length (905 nm) which ensures eye safety (Laser Class 1)

Horizontal Resolution of 0.25°

Vertical Field of View of 3.2°

4 Vertical Layers of 0.8° each

Typical Range: 150 m for other vehicles or up to 50 m for pedestrians

Electronic Control Unit

The Electronic Control Unit (ECU) used in the ibeo.Reference sensor system is an embedded PC. It runs all scan data processings including the fusion of the scan data of all LIDAR sensors within the sensor system and the performance of the object detection and tracking algorithms. It uses an embedded LINUX operating system, installed on a solid state disc.
